Returns the matrix that should be used to render this component. Allows component class to perform graphical distortion to the component not supported by an FTransform NOTE: When overriding this method to alter the transform used for rendering it is typically neccessary to also implementUSceneComponent::UpdateBounds. Otherwise the Local bounds will not match the world space bounds, causing incorrect culling.
